Our bodies are AMAZING!!! I love witnessing its majesty! This second time mom had a precipitous/rapid birth and used chiropractic care throughout her pregnancy & postpartum @cafeoflifedallas “The rhombus of Michaelis (sometimes called the quadrilateral of Michaelis) is a kite-shaped area that includes the three lower lumber vertebrae, the sacrum and that long ligament which reaches down from the base of the scull to the sacrum. This wedge-shaped area of bone moves backwards during the second stage of labour and as it moves back it pushes the wings of the ilea out, increasing the diameters of the pelvis. We know it’s happening when the woman’s hands reach upwards (to find something to hold onto, her head goes back and her back arches. It’s what Sheila Kitzinger (1993) was talking about when she recorded Jamaican midwives saying the baby will not be born ‘till the woman opens her back’. I’m sure that is what they mean by the ‘opening of the back’. “The reason that the woman’s arms go up is to find something to hold onto as her pelvis is going to become destabilised. This happens as part of physiological second stage; it’s an integral part of an active normal birth. If you’re going to have a normal birth you need to allow the rhombus of Michaelis to move backwards to give the baby the maximum amount of space to turn his shoulders in. Although the rhombus appears high in the pelvis and the lower lumbar spine when it moves backwards, it has the effect of opening the outlet as well. “When women are leaning forward, upright, or on their hands and knees, you will see a lump appear on their back, at and below waist level. It’s much higher up than you might think; you don’t look for it near her buttocks, you look for it near her waist.

North Dallas Doula Associates(@northdallasdoulas)分享的贴文 于 张贴

根据《每日邮报》报导,一间位于美国陆伊斯安那州的产后护理中心「Tangi Birth Services」近日在脸书粉专上分享了一张照片,而这张照片最初源自于IG「North Dallas Doulas」,图中可以看见一名女性正以趴着的姿势在分娩,一旁还有几位护理人员,而这名产妇的后背靠近屁股处的皮肤可以很明显地观察到一个突起物,就像是长出了一条短短的尾巴一样,十分神奇。而产后护理中心也在贴文中说明,产妇在进入分娩的第二个阶段时,会有一块骨头向后移动以增加骨盆的直径,帮助生产过程更加顺利,而这也就是所谓的「背部开口」。

不过大部分的人看到这样的情况通常都会有些惊恐,不过贴文中也表示这完全是正常现象,主要目的是给与宝宝在腹中有更大的旋转空间,而且事实上妈妈并不是唯一产生变化的人,宝宝也会为了适应产道大小而进行改变,等同于两人一起为了宝宝自己的诞生而做出了惊人的努力。
